SARS, Nucleocapsid Protein (Severe Acute Respiratory Syndrome)

Antibodies / Antibodies-Infectious Disease SARS

-20°C

Supplied as a liquid in PBS, 0.05% sodium azide.

Synthetic peptides corresponding to amino acids 354-370 of putative SARS nucleocapsid (Genbank accession no. NP_828858).

It has recently been shown that SARS is caused by a human coronavirus. Human coronaviruses are the major cause of upper respiratory tract illness in humans, such as the common cold. Coronaviruses are positive-stranded RNA viruses, featuring the largest viral RNA genomes known to date (27-31 kb). The first step in coronavirus infection is binding of the viral spike protein, a 139-kD protein, to certain receptors on host cells. The spike protein is the main surface antigen of the coronavirus. The most prominent protein in the culture supernatants infected with SARS virus is a 46kD nucleocapsid protein. This suggests that the nucleocapsid protein is a major immunogen that may be useful for early diagnostics.
